LOCOMOTlVE-PILOT AND CAR-COUPLING THEREFOR.

SPECIFICATION forming part of Letters Patent No. 695,684, dated March18, 1902.

Application filed August 23. 1901. Serial No. 72,968 (No model.)

To all whmn it may concern.-

Be it known that I, EDWARD GRAFSTROM, a citizen of Sweden, residing atTopeka, in the county of Shawnee and State of Kansas, have invented acertain new and useful Improvement in Locomotive-Pilots and Oar-Couplers'lherefor, of which the following is a specification.

My invention relates to the improvement of locomotive-pilots andcouplers therefor; and the objects of my invention are to provide animproved construction of coupler-carrying pilot and in conjuctiontherewith to provide superior means for supporting and disposing of thecoupler and to produce certain improvements in details of construction,

and arrangement of parts which will be more fully pointed outhereinafter. These objects I accomplish in the manner illustrated in theaccompanying drawings, in which- Figure 1 is a front elevation of alocomotive-pilot having my improvements. Fig. 2 is a plan View of thesame. Fig. 3 is a sectional view on line a: a: ofFig. 2. Fig. at is aplan View of a coupler which I employ. Fig. 5 is a side elevation of thecoupler-supporting bracket, and Fig. 6 is a plan view of the same.

Similar numerals refer to similar parts throughout the several views.

1 represents the front end sill of the locomotive; 2, the convergingframe bars or ribs of the pilot; 3, the inclined front frame-beam orpilot nose-beam, and 4 the top frame-plank of the pilot.

In carrying out my invention I employ a coupler-supporting bracket-body5, the inner end of which is provided with an angular termination 5,which embraces two or more sides of the sill 1, to which it is bolted orotherwise firmly secured over the central portion of the pilot. Thesupporting-bracket 5 in its outer portion is recessed or bifurcated toform two forwardly-extending jaws 6 and 7,. these jaws being provided intheir central portions with oppositely-located pin-holes 8 and 9 and atpoints inrear of the holes 8 and 9 with oppositely-locatedpin-holes 10and 11.

In carrying out my invention portions of the upper ribs or pilot-bars 2are removed, resulting in the formation of an oblong opening 12 in thepilot-framework, through the inner end portion of which projects thecastin g 5.

13 represents a car-coupler body, the head or coupling outer end portion13 of which may be any suitable or well-known construction which willfacilitate its engagement with the coupler-head of an adjacent car. Therear or shank portion 13 of the coupler is, however, formed with anenlargement, which results-in theproduction of separated jaws 14. and15, and, as indicated in the drawings, the j aws 14 and 15 of thecoupler are adapted to embrace the upper jaw 6 of the bracket, the lowerjaw 15 of the couplerhavinga suitable bearing on the upper side of thelower jaw 7 of the bracket.

16 represents a vertical pivot-pin which, as shown, is designed topivotally connect the coupler and bracket by passing loosely throughpin-openings 13 in the coupler-jaws and through the bracket pin-openings8 and 9.

17 represents a retaining-pin which passes looselythrough an opening inthe upper horizontal frame beam 4 of the pilot, thence through thebracket-opening 10, a slightlyelongated pin-hole 13 in the lower jaw ofthe coupler, and through the lower bracket pin-hole 11.

It will be observed that when the coupler is supported in the positionshown in the drawings-that is, extended forwardly with the pins 16 and17 inserted-said coupler-body will be held in position for coupling withan adjoining car and that it may have such necessary lateral swingingmotion as may be permitted by the degree of elongation of the opening 13in the lower jaw of the coupler. When the coupler is not desired foruse, however, it is obvious that the pin 17 may be withdrawn and thecoupler-body swung horizontally on its pivot-pin 16 until it enters theopening 12 of the pilot-frame, in which posit-ion it will be out of theway. When the coupler is thus thrown back, the pin 17 may be inserted inan opening 13 In case a sufficiently-low form of pilot-frame is employedit will be seen that the coupler might be swung horizontally out of theway in the pilot-frame would be avoided. Although my improved coupler isshown and described as particularly designed for use onlocomotive-pilots, it is obvious that the vertically pivoted andhorizontally swinging coupler, such as herein described, might beemployed in connection with a tender or car.

It is customary to extend the air-brake pipe ends or other fittingsbeyond the surfaces of the pilot-ribs or frame-bars and to permanentlyclamp thereto air-conducting hose. In order to avoid this undesirableprojection of the air-brake pipe ends or other extensions beyond thepilot, it is obvious that a suitable or well-known form of hose-couplingmay be secured between the pilot-ribs, flush with the front surfacesthereof, thus permitting the hose to be coupled or removed therefrom andcarried on the locomotive, preserving the hose from injury and at thesame time clearing the pilot from undesirable attach men ts orproject-ions.

It will be readily understood that the jaws 14 and 7 of the couplermight be consolidated into the form of a tongue which could be insertedbetween the jaws 6 and 7, or that the twolatter jaws mightlikewise beconsolidated to form a tongue which could be inserted between the jaws1i and 15 of the coupler.

Having now fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. In a locomotive-pilot and car-coupler therefor, the combination withthe pilotframework having a recess 12 in its upper portion, of a fixedbracket extending from the locomotive-sill and a car-coupler connectedwith said bracket by a vertical pivot-pin and adapted to be swung intosaid pilot-recess, substantially as specified.

2. In a locomotive-pilot and car-coupler,the combination with apilot-frame having a recess 12 in its upperportion and a fixed bracketextending from the locomotive-sill, of a carcoupler mounted to swing inits bracket on a vertical pivot and a detachable stop-pin adapted tointersect said bracket and car-coupler, substantially as specified.

3. Inalocomotive-pilot and car-coupler,the combination with thepilot-frame having an upper recessed portion 12, a fixed bracketextending from the locomotive-sill and having separated jaws, of acar-coupler having its rear portion bifurcated to embrace one of saidbracket-jaws, a vertical pivot-pin hinging said coupler and bracket anda detachable stoppin intersecting said coupler-and bracket,substantially as specified.
